-.SH NAME
-webcollage - decorate the screen with random images from the web
-.SH SYNOPSIS
-.B webcollage
-[\-display \fIhost:display.screen\fP] [\-root] [\-verbose]
-[\-delay \fIsecs\fP] [\-timeout \fIsecs\fP] [\-background \fIbg\fP]
-[\-filter \fIcommand\fP] [\-filter2 \fIcommand\fP]
-.SH DESCRIPTION
-The \fIwebcollage\fP program pulls random image off of the World Wide Web
-and scatters them on the root window. It finds these images by doing
-random web searches, and extracting images from the returned pages.
-It places the images on the root window by using the
-.BR xv (1),
-.BR giftopnm (1),
-and
-.BR djpeg (1)
-tools.
-
-\fIwebcollage\fP also works as a CGI program: simply make a symbolic
-link to the \fIwebcollage\fP executable called \fInph-webcollage.cgi\fP.
-If this program sees that it is being run as a CGI, then it will behave
-appropriately. (The generated web page will list the images one after
-another, rather than tiling them together.)
-
-\fIwebcollage\fP is written in
-.BR perl (1)
-and requires Perl 5.
-.SH OPTIONS
-.I webcollage
-accepts the following options:
-.TP 8
-.B \-root
-Draw on the root window. This option is manditory: drawing to a window
-other than the root window is not yet supported.
-.TP 8
-.B \-verbose \fRor\fP \-v
-Print diagnostics to stderr. Multiple \fI-v\fP switches increase the
-amount of output. \fI-v\fP will print out only the URLs of the
-images; \fI-vv\fP will print all the commands being run; and \fI-vvv\fP
-will print more than you care about.
-.TP 8
-.B \-delay \fIseconds\fP
-How long to sleep between images. Default 1 second. (Remember that
-this program probably spends a lot of time waiting for the network.)
-.TP 8
-.B \-background \fIcolor-or-ppm\fP
-What to use for the background onto which images are pasted. This may be
-a color name, a hexadecimal RGB specification in the form '#rrggbb', or
-the name of a PPM file.
-.TP 8
-.B \-timeout \fIseconds\fP
-How long to wait for a URL to complete before giving up on it and
-moving on to the next one.
-Default 30 seconds.
-.TP 8
-.B \-filter \fIcommand\fP
-Filter all source images through this command. The command must take
-a PPM file on stdin, and write a new PPM file to stdout. One good
-choice for a filter would be:
-.EX
-webcollage -root -filter 'vidwhacker -stdin -stdout'
-.EE
-.TP 8
-.B \-filter2 \fIcommand\fP
-Filter the \fIcomposite\fP image through this command. The \fI-filter\fP
-option applies to the sub-images; the \fI-filter2\fP applies to the
-final, full-screen image.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number.
-.TP 8
-.B XENVIRONMENT
-to get the name of a resource file that overrides the global resources
-stored in the RESOURCE_MANAGER property.
-.SH FILES AND URLS
-.TP
-.I /usr/dict/words \fRor\fP /usr/share/lib/dict/words
-To find the random words to feed to search engines.
-.PP
-.I http://random.yahoo.com/bin/ryl, http://image.altavista.com/
-To find random web pages.
-.SH BUGS
-When drawing on the root window, it always uses the default colormap.
-This is actually a limitation of xv. But regardless, when using this
-program with xscreensaver, it must be given the \fBdefault-n\fP
-visual specification (see the
-.BR xscreensaver (1)
-manual for more details.)
-
-Only the GIF and JPEG image formats are supported.
-
-Transparent and animating GIFs are not supported.
-
-It's slow.
